STEREOLİTHOGRAFİ EKLEMELİ İMALAT YÖNTEMİYLE FARKLI DOLULUK ORANLARINDA ÜRETİLEN NUMUNELERİN MEKANİK ÖZELLİKLERİNİN İNCELENMESİ

Eklemeli üretim (EÜ), yalnızca prototip oluşturma konusunda değil, aynı zamanda nihai tasarımlara basılı parçaların dahil edilmesinin kolaylığı nedeniyle de endüstride bir değişimi yönlendiriyor. Stereolithografi (SLA), 3B yazıcı teknolojisi kullanılarak karmaşık parçaların hızlı üretilebildiği ve platform üzerinde dikey olarak çalışan bir eklemeli üretim teknolojisidir. Bu teknikte akışkan reçine, lazer ışını ile 3B parçalar kullanılarak katman katman işlenerek model elde edilmektedir. Diğer üretim tekniklerinden farklı olarak model şeffaf ve dayanıklı bir yapıdadır. SLA ile üretim yapan 3B yazıcılarla üretilen parçaların mekanik özelliklerinin bilinmesi, parçaların verimli çalışması ve üretim tekniğinin kullanımının yaygınlaşması açısından önemlidir. Bu çalışmada, Flashforge Foto 6.0 3B yazıcı ile Anycubic UV reçine malzeme kullanarak farklı doluluk oranına sahip 15 adet çekme ve 15 adet basma olmak üzere toplamda 30 adet numune üretilmiştir. Doluluk oranının mekanik özellikler üzerindeki etkileri araştırılmıştır. Sonuç olarak, %25, %50 ve %100 doluluk oranının, SLA tabanlı 3B yazıcı ile üretilen çekme ve basma numunelerinin mekanik özellikleri üzerinde etkisi olduğu tespit edilmiştir. Kullanılan doluluk oranları arasından en yüksek çekme ve basma mukavemetinin “%100” doluluk oranında olduğu belirlenmiştir. Bu değerler sırasıyla 10.095 MPa ve 10.098 MPa’dır. Ortalama çekme ve basma mukavemeti değerlerinin doluluk oranı arttıkça yükseldiği gözlemlenmiştir.

INVESTIGATION OF THE MECHANICAL PROPERTIES OF SAMPLES PRODUCED AT DIFFERENT FILLING RATIOS BY STEREOLITHHOGRAPHY ADDITIVE MANUFACTURING METHOD

Additive manufacturing (AM) is driving a change in the industry, not only in prototyping, but also because of the ease of incorporating printed parts into final designs. Stereolithography (SLA) is an additive manufacturing technology that can quickly produce complex parts using 3D printer technology and runs vertically on the platform. In this technique, a model is obtained by processing the fluid resin layer by layer using 3D parts with a laser beam. Unlike other production techniques, the model is transparent and durable. Knowing the mechanical properties of the parts produced with 3D printers that produce with SLA is important for the efficient operation of the parts and the widespread use of the production technique. In this study, a total of 30 samples, 15 tensile and 15 compression, with different filling ratios, were produced using Flashforge Photo 6.0 3D printer and Anycubic UV resin material. The effects of filling ratio on mechanical properties were investigated. As a result, it has been determined that 25%, 50% and 100% filling rates have an effect on the mechanical properties of the tensile and compression samples produced with SLA-based 3D printer. It was determined that the highest tensile and compression strength among the filling ratios used was “100%” filling ratio. These values are 10.095 MPa and 10.098 MPa, respectively. It has been observed that the average tensile and compressive strength values increase as the filling ratio increases.
